1. Introduction to ps-locale-sk_SK-12.5.1.4000-1.cop.sgn

This digitally signed COP file provides comprehensive Slovak language support for Cisco’s enterprise collaboration systems. Designed for CUCM 12.5.1 deployments, it implements:

  • ​​Diacritical character handling​​ for Š/š, Č/č, Ž/ž in call detail records
  • ​​Local legal compliance​​ with Slovakia’s Act No. 181/2014 on data retention
  • ​​Time zone optimizations​​ for Central European Time (CET/CEST) transitions

Certified under Cisco Collaboration System Release 12.5.1 SU4, it supports organizations requiring ISO 639-3 “slk” language code compliance for EU regulatory mandates.

2. Technical Specifications and Enhancements

    • Number formatting with thousand separators (1 234,56 €)
    • Legal document templates compliant with Slovak telecommunication laws

2.2 Cryptographic Validation

The .sgn file utilizes:

  • ECDSA-384 digital signatures with Brainpool P384r1 curve
  • SHA3-512 hashing for firmware integrity checks
  • Hardware-backed signing via Cisco Secure Boot Chain

2.3 Performance Improvements

  • 25% faster directory search performance for Slovak character sets
  • Support for 1024 concurrent SIP sessions with Slovak carriers
  • Reduced memory allocation through optimized UTF-8 encoding
